DEVICE ron nxrnacrme MEASURED QUANTITIES or e Ass F' QM sMELTING:

To all pvhom it may concern Be it known that I,.HEIN IoH SEVERI'N,

of Sasbach, near Achern, in the Grand Duchy of Baden, in the GermanEmpire,

have invented certain newv and useful Improvements in Devices forExtracting Measured Quantities of Glass'from Smelting- Furnaces.

The present invention relates'to a'device by means of which glass may be extracted from a smelting furnace in given quantities in order to be used for further manipulation,and it has reference in particular to such devices as consist of an intermediate ceptacle according to this present invention be fed from the furnace to the hollow cyl-- receptacle or vessel which is located in the furnace or an extenslon thereof, this 1n;

termediate receptacle being provided with glass inlet and outlet openings and with a' device whereby the glass can be pressed out of the intermediate receptacle. For this purpose either a pressure block or com pressed air can be used, the pressure block being raised and lowered in a correspondingly formed chamber of the intermediate receptacle. f

-The arrangement of the intermediate reis such that a rotary hollow cylinder can be used instead of a piston or pressure block which is raised and lowered. This hollow cylinder is providedfwith inlet and outlet openings, which can bebrought into regis tration' with the inlet and outlet openings of the intermediate receptacle according to whether it' is desired that=theglass should inder or pressed from the hollow cylinder into position for further manipulation.

. glass is tobe manipulated, the mouth of the The intermediate receptacle can be located either on the bottom of'the furnace or the extended portion of same and the hollow cylinder can be open underneath and be in constant communication with the g SS Outlet opening, or thesaid intermediate receptacle can be suspended from the roof. of the furnace in the molten mass and the hollow cylinder can be closed underneath so that it only comes periodlcally in communication with the outlet openingof the intermediate receptacle. g

According to the purpose for which the intermediate receptacle can be directed upward, and over said mouth an opening can be made in the roof of the furnace which can I Specification of Letters Patent. Application filed September 1, 1910i Serial No. 580,061.

be closed by a plate. Through this openmg the preliminary or filling mold can be introduced into the furnace and be placed on.

the mouth of the intermediate receptacle. The outlet pipe of.the intermediate receptacle can also have its mouth directed downward in case the mold is introduced into the furnace from below or in case it has to be brought before an opening provided inthe .bottom, In this case the glass flows from the mouth of the rising or outlet pipe of the intermediate receptacle by gravity to the mold.

Although the intermediate receptacle will be generally arranged to be mounted in the ceptacle, the latter is raised until the mouth of its rising passage engages with the under edge of the preliminary or filling mold. In orderto reduce the time necessary for extracting the glass from the furnace, the

preliminary or filling mold can be connected an arrangement whereby a vacuum the glass into the preliminary or filling mold in two ways, that "is, by the :pressing applied. It will be plea-r that, in the latter case, the time required for filling the glass into the preliminary .m'old is considerably reduced and the mold is less exposed to the gases of high temperature of the furnace and the mold is thereby rendered more durable.

. 'A further advantage consists in the considerable reduction of time necessary for making single objects such as bottles, and in the correspondingly increased capacity of the machine. The inventionis shown in the accompanying drawingsin several suitable forms, in which-- Figure l isa vertical section through that part of the furnace which comes into ques arrangement orby suction of the air out of K the preliminary mold,*or both ways can be tion, and the arrangement serving to extract the glass. Fig. 2 shows a modification p with an inlet port 3 for the glass and a risthe receptacle 2, the hollow cylinder 5 ing outlet pipe 25, the mouth. of which is designated by 4. In the hollow space 26 of is so suspended that it can be rotated by ratchet gear 21 to the extent of 90 at a-time. The

i hollow cylinder is provided with perforations' at two places diametrically opposite each other and which are alternately broughtinto registration with the inlet port .By means of .the pipe '15 which is in communication with thehollow cylinder 5, the interior-of the cylinder can be filled with compressed air.

The machine for forming the hollow glass bodies is placed before the furnace in the usual way and consists, in the construction shown, of the cyllnder 10 1n which a vert1-.

cal shaft 9 is so located that it can be raised, lowered and rotated. On an arm 8 keyed to the shaft 9 is a preliminary mold 11- of two parts which are closed by the headmold 12 which is likewisefastened to the arm 8. A suction pipe 6 is coupled to the head-mold in the usual way and is provided with a stop-cock l4.

By means of this arrangement the method of producing hollow glass bodies resolves itself into the following :During the inter val between the making of two bottles, the

.hollow cylinder'5 is so rotated that one of its perforations 22 comes into registration with the inlet ort 3 ,and the-glass enters into. the cylin er 5. If the preliminary mold 11 of the machine is now lowered on to the mouth 4 of the outlet passage 25 for the purpose of being filled, the cylinder 5 is simultaneously rotated to' the extend of 90" in the position shown. The mold can now be filled in two ways (1) By compressed air being fed into the Interior of the cylinder 5 through the pipe 15. The perforations 22 of the cylinder being closed in this position, the glass has no other course but to pass from below into the outlet passage 25 and to pass through its mouth 4 into the mold. The passage of the glass can, however, be made easier and be accelerated by (2) Opening the cock 14 of the suction pipe 6 and creating a vacuum, Theglass is thus made to enter the mold both under the influence of the pressure of the "compressed air and of the vacuum created in the head-mold and the preliminary mold.

For obtaining both the pressure and the vacuum, one and the same arrangement is preferably used as will now be explained with reference to the draw1ngs:

In the cylinder 16 is the plunger'17 the connecting rod of which is extended so as 'to carry two further plungers 27 and 28 in supplementary cylinders 18 and 19. The cylinderlS is in communication with a con-' duit for'compressed air (not shown) so that,'

on reversing, the air can enter either above or below the plunger 27 and thus cause the plunger 17 in the cylinder 16 to be raised or lowered. The-cylinder 19 is supposed to be.

a retarding cylinder filled-with glycerin, its action being regulated by a cook 29 in the pipe 20 through which the flow is reversed at each stroke of the piston.

' The cylinder 16 acts over the plunger 17 at first as a pressure pump, the pressure being conducted to the hollow space of the cylinder 5 through the pipe 15, but below the plunger it acts as a vacuum pump by means of its connection with the suction vacuum in the preliminary mold and head-" mold. The succeeding downward stroke of the plunger 17 to its starting position, as shown, will have the effect of accelerating the entry of the glass in the cylinder 5 by suction. i

The amount of the suction is regulated to x the required degree by means of. a backpressure valve 24 attached to the cylinder 16, as the glass might otherwise be easily sucked up into pipe 15 where it would congeal and interrupt the communication. It is preferable to allow the air passing through the backpressure valve tocome through a pipe 30 direct from the hot furnace in order to avoid cold air entering the hollow cylinder when the glass is being pressed out, as it would cause cracks in the glass.

The intermediate receptacle shown in Fig. 2diflers from that shown in Fig. 1 in that it is not placed on the bottom of the a fiange31 at its upper end by means of which it can rest on the edge of the opening of the furnace.

The further modified forms of intermediate receptacle, shown in Figs. 3-5 are also. suspendedfin the furnace in the same man ner asthe form shown in Fig. 2,'but they differ in {that the hollow cylinder 82 is under which opening the intermediate mold serving to receive the molten glass. to loev closed on all sides. At its lower end the cylinder 32' is provided with two openings 33 which are alternately brought into registration with the glassinlet openings 34 and the glass outlet opening25 in the intermediate receptacle 2, as is clearly shown in Fig. 4:. i

While the-arrangements shown in Figs.

14 are suitable "for the production of ,bottles, the arrangement shown in Fig. 5

can be used with advantagefor producing plate glass or wide-necked hollow glass bodies. This arrangement only differs from those previously described in that the glass outlet passage 25 of the intermediate receptacle 2 is provided with a downwardly directed mouth 36 which extends toward an opening 37 in the bottom of the furnace manipulated is brought. For inclosing the furnace a block'35 of chamotte is used.
